Detailed Description

The utility model will be further described with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, a lactobacillus liquid culture apparatus comprises a sealed reaction tank 1, wherein the sealed reaction tank 1 is used as a main container for lactobacillus liquid culture and adopts a sealable structure to prevent external pollutants from invading and affecting the liquid; meanwhile, in order to facilitate observation of the culture condition and progress, the sealed reaction tank 1 is made of transparent materials such as toughened glass.

The base platform 5 is arranged at the bottom of the sealed reaction tank 1, the heating roller 6 extending upwards is vertically arranged at the center of the base platform 5, a certain constant temperature needs to be kept in the specific culture process of lactobacillus, the heating roller 6 can slightly heat the inside of the sealed reaction tank 1, the environment where each culture container is located in the culture process is ensured to be at a proper temperature, and meanwhile, the inside of the sealed reaction tank 1 is kept dry.

In order to make the heating range wider and more uniform, a plurality of sets of heat conduction fins 7 are uniformly installed on the outer edge of the heating roller 6 to improve the heat conduction range and efficiency. The fins of the heat conducting fins 7 are used for enhancing heat transfer, and the heat transfer mode is that liquid metal in the liquid absorption cores inside the fins is vaporized and condensed to transfer heat.

The base station 5 is further provided with an annular slide rail assembly 4, the slide rail assembly 4 adopts a conventional circularly movable assembly, for example, the slide rail assembly comprises a slide block and a guide rail, the slide block is sleeved on the guide rail, and the slide block can slide along the guide rail.
